subject: Unit Testing: Efficient Testing Tools And Techniques [print this page] Unit Testing is a software verification and validation tool that is used by the developers to test different modules of the program & if the individual unit of coding are best suited for them. The unit is the smallest part of the programs that are used for testing. There are two types of programming that is procedural and modular. On the basis of type of programming the selection of testing is done. For the procedural programming a unit testing tool is used unless a unit may be an individual function or it can be a procedure.
Unit testing allows the developers to break down the code into small parts known as units but keep in mind that the module still works correctly. The testing procedure for this will be written correctly that is write the test cases for each and every function along with its methods so that if there is any error is recognized in the code it can be easily identified and solved. The readily available unit testing tools makes this work easy for the developer to check and fix the problem.
The main purpose of Unit Testing is to simplify the code by reducing its uncertainty in their units themselves and the source code can be used in the bottom-up approach style. After applying this procedure you can easily integrate the code for applying another testing technique. Despite the thinking of programmer the integration testing is highly dependable on the manual work than the unit testing approach.
We all know nothing is perfect everything has some limitations. Same case with the unit testing since it is easy to use and check the program by dividing it into units. But, it can only check the program executable function error as it has limitations not to fetch the integration errors of the source code. Unit testing can give you where the errors are there in the code means it will only helps you in showing the presence of errors in the code they cannot show the absence of errors in the source code.
Unit testing is based on automated testing tools unless it works better manually because the IEEE approach cannot favor more than one technique. As we all know the main purpose of automated testing is to isolate unit verify it and then validate the correctness of the units. That is why automation unit testing tool can work efficiently for it and also enables number of benefits for the programmer.
